Carl Zeiss lens Carl Zeiss T* coatings
82% less reflection than conventional
lens elements, for maximum contrast
and perceived sharpness.
The difference that T* coatings makes is obvious, even
to the naked eye.
All Carl Zeiss lenses in Cyber-shot
use special coatings to cut down internal
reflections. The Carl Zeiss lenses designed
for the a100 Digital SLR go even further.
They feature optical elements with the Carl
Zeiss T-star coatings. These coatings reduce
internal reflections at the glass-to-air
surfaces. This suppresses lens "flare"
or "ghosting" that can sap an image of
its contrast and punch. The T* coatings
mean 52% less reflection than a standard
Carl Zeiss ® lens – and an impressive 82%
less reflection than a conventional lens.
You get notably more natural, more
vibrant images.
Optical zoom lens
Greater freedom in composition, including
the ability to get close to your subject or
pull back for a wider view.
Optical zoom lenses set you free. You
can zoom in tight on distant subjects,
great for shooting children's sports or
recital performances. For example, the
full telephoto position of the DSC-H7
and DSC-H9 brings you incredibly close
(15x zoom at 465mm, 35mm equivalent).
A mild telephoto setting (about 100mm)
is especially flattering for portraits, because
it enables your subject to fill the frame
while you stand back far enough for a
natural perspective. Finally, you can use

zoom always delivers the full performance
of the camera's image sensor.
Compact zoom lens
The quality of Carl Zeiss optics and the
power of up to 5x zoom in ultra-small,
ultra sleek cameras.
Sony has an extensive background in
microelectronics and micromechanics.
You can see this expertise in products like
Sony camcorders and ultra-slim laptop
computers. So it's no wonder that we have
our own, unique perspective on zoom lens
design. A compact zoom lens needs to
incorporate zoom optics, zoom mechanics,
shutter and focus actuators. But Sony has
found ways to slim these lenses down
considerably. That's why so many
Cyber-shot ® cameras incorporate an
optical zoom lens that combines good
zoom range and good lens speed in a
design that retracts into the camera body.
And some Sony cameras go further still.
Starting with the precision of the Carl
Zeiss Vario-Tessar ® design, Sony created
a folding-optical-path lens for the DSC-T1.
You'll find that same inspired design on
today's T Series cameras. It never needs
to extend forward from the camera body.

Sony makes it easy to capture beautiful
images of small objects like jewelry, coins,
stamps and flowers. Macro focus mode
enables you to focus on objects just a few
inches away from the lens!
Magnifying Glass mode
Capture detail not visible to the naked eye.
Film cameras are limited in their macro

Magnifying Glass mode enables you to
position the camera a mere 1 centimeter
(0.4 inch) away from the subject! So you
can see (and capture) detail not visible

magnification depends on the distance
from the camera to the subject.
